288 Quarterly Report of the Chemical Committee for December, 



Accordingly, on January 1st, the Secretary wrote a letter 

 callincr attention to the advertisements which had appeared in 

 the ' Mark Lane Express ' and ' Bell's Weekly Messenger ' of 

 August 19th, 1872, announcing the formation of an Association 

 entitled " The Hull Pure Linseed-cake Association," the mem- 

 bers of which had resolved " that from and after this date no 

 other cakes than pure linseed-cakes shall be sold or described as 

 ' Linseed-cakes.' " These and other resolutions were come to 

 at a meeting of seed-crushers and cake-merchants of Hull, on 

 August 14th ; and the report of that meeting (taken from the 

 'Yorkshire Post' of the 16th) was published in the Society's 

 'Journal' issued to its members — Part 2, of 1872. 



Particulars were then given of the two cases in question, 

 showing a departure from these resolutions on the part of the 

 members of the Association referred to. 



In one of these cases the following warranty was given by the 

 vendor at the time of purchase : — 



Wareanted Puke Linseed-cakes. 



Sold 



Pure Linseed-cakes, at £11 12s. 6d. 2^er ton, ivliich are 

 made entirely from fine, sound, screened linseed, and 

 free from any adulteration. 



THIS WARRANTY 'SUBJECT TO THE ANALYSIS OF 

 PROFESSOR ANDERSON. 



In the other case the cake was invoiced as " Pure Linseed- 

 cake," at IIZ. per ton, " nett cash," and each cake was stamped 

 with the word " Pure." 



Dr. Voelcker found that both samples of cake were of inferior 

 quality, made from badly-screened linseed, containing many 

 small weed-seeds, much starchy matter, and from 4 to 4^ per 

 cent, of sand. They were also poor in oil and albuminous (flesh- 

 forming) compounds. The following are the analyses of the 

 two samples of cake : —
